2 Claims.

This invention relates to closures for bottles and other containers, itsobject being to provide an improved construction which, while allowingadequate access to and egress of the contents of the container, cannotbe completely removed therefrom or readily or inadvertently released oropened by children by reason of the degree of physical efiort and skillrequired to operate it, which eiiort and skill would not normally bewithin the capabilities of a child.

According to the present invention the improved closure for bottles andother containers comprises an annular outer member at the upper part ofthe container, said outer member having a shoulder of reduced diameterand serving to define an outlet opening for the container, a U-shapedinner member slidably arranged therein in inverted position with thefree ends of its arms within the container, the distance between thetips of the arms being greater than the diameter of the reduced shoulderof the outer member whereby the inner member is prevented from becomingcompletely removed from the container by contact of the tips of the armswith the shoulder, and a sprung press-cap inseparably connected to theinner member and adapted to grip onto the exterior of the outer memberwhen said press-cap is placed over the outer member and snapped intoclosed position.

The arms of the inner member may have, at their tips, outwardly extendedportions the outer ends of which are a greater distance apart than thediameter of the shoulder so as thereby to contact the shoulder andprevent complete removal Of the inner member.

An embodiment of the invention is shown by way of example in theaccompanying drawing which is a central vertical section of a containerhaving a closure shown in open position.

In this drawing, a cylindrical container 53 has at its upper part ashoulder '56 of reduced diameter. 55 is an inverted U-shaped innermember having at the tips of its arms outwardly extending portions 55which engage as shown beneath the shoulder 56 so as to prevent completewithdrawal of the inner member 55 from the container. At the uppercentral portion of the inner member there is secured, by a rivet 55 asprung press-cap 54 of the well-known kind consisting of a centraldished portion 5'! having a depending peripheral flange consisting ofsegments 56. The position of the press-cap shown is one of its twostable positions. If the segments 58 of the flange are pressed radiallyinwards, the dished portion 51 is snapped into a domed shape withconsequent inward movement of the free ends of the segments 58. If thepress-cap and inner member are first moved fully inwardly, theabove-described action takes place and the segments engage into thecorresponding exterior contour of the shoulder 56,

I claim:

1. A closure for bottles and other containers comprising an annularouter member at the upper part of the container, said outer memberhaving a shoulder of reduced diameter, and serving to define an outletopening for the container, a, U-shaped inner member slidably arrangedtherein in inverted position with the free ends of its arms within thecontainer, the distance between the tips of the arms being greater thanthe diameter of the reduced shoulder of the outer member whereby theinner member is prevented from becoming completely removed from thecontainer by contact of the tips of the arms with the shoulder, and asprung press-cap inseparably connected to the inner member and adaptedto grip onto the exterior of the outer member when said press-cap isplaced over the outer member and snapped into closed position.

2. A closure for bottles and other containers comprising an annularouter member at the upper part of the container, said outer memberhaving a shoulder of reduced diameter and serving to define an outletopening for the container, a U-shaped inner member slidably arrangedtherein in inverted position with the free ends of its arms within thecontainer, outwardly extended portions at the tips of the arms of theinner member, the outer ends of the outwardly extended portions being agreater distance apart than the diameter of the shoulder of the outermember whereby the inner member is prevented from becoming completelyremoved from the container by contact of the outwardly extended portionswith the shoulder, and a sprung presscap inseparably connected to theinner member and adapted to grip onto the exterior of the outer memberwhen said press-cap is placed over the outer member and snapped intoclosed position.
